Crystal engineers manufactures full bore electro magnetic flow meters, model m300, manufactured by combined instruments, australia. These flow meters are quality wise at par with the other leading manufacturers in the world. Sometimes these meters have proven better accuracy than the other meters. These meters are awarded iso 9002. They sense 0 to 100 percent flow in the pipe. Other features include constant cleaning action using electrolysis; accuracy is some times less than 0.15 percent of the flow; sensor body, ie, primary element class is ip 68, and it is submersible; transmitter is micro-processor based with ip 68 weather proof features; constant check coil electrodes and other operations; and the manufacturer has facility for testing up to 1200 mm pipe.
